|Breeding Corydoras xinguensis
by Mark Bryson
fter reading an article on the internet by Kristian Adolfsson "Dry & Rainy Seasons Tank" I decided to set up similar conditions in the hope of my wild caught C. xinguensis breeding. (3 males, 2 females).
Corydoras xinguensis - pair
Description: C. xinguensis are from the Rio Xingu Estado, Mato Grosso area of Brazil. Base colour grey, dark spots cover the body down below the level of the lateral line. Lower body and belly region plain grey. On close inspection spots can be seen on the dorsal and pectoral fin spines, caudal fin also has light spotting. Size 3.5 4cm.
Breeding Tank & Maintenance: Tank 18"x 8"x 8" with a small glass trough 8"x 2"x 2" placed to one side of the tank. This contained silver sand and planted with Indian Fern. Filtration: Air-driven sponge plus box filter filled with ceramic rings and a small amount of coral gravel to stabilise the pH of 6.5.
Feeding: I try to feed my fish at least twice daily with a good varied diet consisting of the following, Tetra Prima, frozen bloodworm/ black mosquito larvae and live grindal worms.
to Breed (Stage 1)
Fry: When the eggs hatch the fry are a grey ball with a tail, 2mm total length. Day 2 they were free swimming. Feeding for the first two days with diluted Liqufry, followed on day three with microworm culture. Very soon they were eating newly hatched brine shrimp, fed little and often. 50% water changes were carried out daily using water from the breeding tank. Five days old the fry were starting to develop some speckling across the face and head. Seven days old the spots were over the face and down their back, they now resembled Corydoras catfish. At this stage the fry were transferred from the 4" hatching tank to a 7" cube with a sponge filter. Also added in this tank a piece of weighted Indian Fern, this provided refuge for the fry. As they progress they will be moved to a larger tank. The original fry were removed from the parents tank, within ten days more fry, approximately two days old, were siphoned out by accident while doing a water change. Any further fry in the parents tank will be left there. These will be monitored as to their progress, comparing them with the 25 fry that were removed as either eggs or fry.
